onions have an array of chemical compounds including sulfuric acid. The acids help break down the organic buildup on the grill. So while a brush is using mechanical abrasion to knock off the organic buildup, an onion will chemically break down bonds, including the bonds to your grill
My buddy is in remediation and is a chemical whiz with cleaning. I followed up with him and he said the onion is really cool because there are multiple chemical reactions happening from the acid and other compounds.
The water in the onion is turned to steam from the heat which helps it permeate the char and increases the rate of reactivity. The acids meanwhile are dissolving some of the simple organic bonds The steam and acids actually cause hydrolysis which breaks down more complex oranges bonds
apparently onions are awesome and I'm never going to hear the end of it. So now you must all suffer in kind.
he called me to talk about cleaning vinegar 😂 I want to blame yall, but I knew this would happen
Hahahaha! That's awesome.
lol I always love hearing from him. Even if it's painfully detailed information about cleaning.
It'll make your grill taste good, too! Win win!
